COPY-HOLDER.

Application filed March 30, 1918., Serial No. 225,712. Renewed June 24,1919.

To all whom it may concern:

Be it known that I, ELMER GRAHAM, a citizen of the United States, and aresident of NVray, in the county of Yuma and State of Colorado, haveinvented a new and Improved Copy-Holder, of which the following is afull, clear, and exact description.

This invention relates to copy holders for use by typ'ists or othersmaking transcripts of records and has particular reference to a deviceof this character that is designed to hold in a convenient and reliablemanner a more or less voluminous quantity or roll of the matter beingcopied.

Among the objects therefore of the invention to provide a copy holdercomprising a hollow cylindrical casing, having two parts hinged togetherlongitudinally of the casing and having means to hold the parts closedbut with the sheet or sheets being copied projecting radially fromwithin the casing along the joint or meeting line of the two easingparts, while the bulk of the matter is housed within the casing.

A further object of the invention is to provide certain improvementsrelating to the spacing means controlling the rotation of the casingaccording to predetermined angular amounts, such amounts beingcalculated according to the width of the lines or other conditions.

Another object of the invention is to provide improved means forcontrolling the gripping of the paper and the releasing of the paperwith respect to the casing.

With the foregoing and other objects in view the invention consists inthe arrangement and combination of parts hereinafter described andclaimed, and while the invention is not restricted to the exact detailsof construction disclosed or suggested herein, still for the purpose ofillustrating a practical embodiment thereof reference is had to theaccompanying drawings, in which like reference characters designate thesame parts in the several views, and in which- Figure 1 is a frontelevation of the casing and parts immediately associated therewith.

Fig. 2 is an elevation of the left end of the device with the lowerportions in section on the line 2-2 of Fig. 5.

Fig. 3 is another elevation of theright end of the device.

Fig. 5 is a vertical section of the base on the line 55 of Fig. 2.

Fig. 6 is a sectional detail on the line 6-6 of Fig. 3

Fig. 7 is an enlarged view indicating the means to rotate or control therotation of the casing, and Figs. 8, 9, 10, and 11 are diagrams showingthe different stages of the operation of the bail upon the sheet ofpaper during the operation of the device.

Referring now more particularly to the drawings I show a base 10 of anysuitable nature providing for the support of a standard 11 in uprightposition. This standard is shown as comprising two plate membersanchored to the base by screws or bolts. Between the upper ends of theplates is clamped an arm 12 by means of a clamping bolt 13 having awinged nut for hand operation. In the upper end of this arm 12 isclamped a crossbar 14 'by means of a bolt 15 whereby the crossbar 14 maybe adjusted angular-1y around its axis irrespective of the inclinationof the upright arm 12 with respect to its clamping bolt 13.

The main part of the copy holder comprises a hollow cylindrical drum orcasing 16, the end portions of which are journaled coaxially in a pairof brackets 17 and 18 extending forward parallel to each other from theends of the crossbar 1 1. The pivot.

means comprises a short shaft 19 for each end of the casing having onits inner end a binding nut 20 and on its outer end a finger piece 21whereby the casing may be rotated conveniently and quickly by hand fromeither end. Said casing is divided longitudinally along a plane at oneside of the axis of rotation thereof, the two parts 16 and 16 thereofbeing hinged together around an axis 22 represented by a rod extendingthe full length of the casing through a pair of cars '23 formed on oneof the parts and overlappingthe perforated portions of the other part. Aspring 24 is arranged between the two parts of the casing in anysuitable manner so as to tend to throw the cover portion 16 open. Asindicated this spring has its ends fixed to studs 2 1 and 24 fixed tothe parts 16 and 16 respectively. The force of this spring to throw theeasing open is limited by means of a link 21 pivoted to the stud 24: andhaving a slot through which the stud 24: projects. The

r The outer action of the spring, however, is normally resisted by apair of catches 25 secured upon the ends of a rod 26 extending throughthe front portion of the casing just below the line of contact betweenthe two'free edges of the casing parts. These catches 25 cooperate withlugs-27 extending from; the

ends of the part 16", and since the catches are both mounted rigidlyupon the same rod 26 they are both moved in unison. A spring 28 coiledwithin the casingaround the rod 26 tends to hold the catches in lockingposition or engaged overthe lugs 27. -When the portion 16 of. the casingis swung to lts' closed position the lugs 27 ride over the cam portions25 of the catches soas to deflect the catches against the, force of theSPIHIQ' 28 for the purpose of allowing the lugs 2 to snap in behind thehook portions of the catches. When the lid portion of the casing is openthe catches 25' are maintained in proper position to be engaged by thelugs 27 by means of a stop lug 29 carried by one orbothof the ends ofthemain portion 16*. end of one catch 25 is provided with an outwardlyprojecting wing 30 whereby the operator by the use of his thumb orfinger may release such catch from' its lug'27 and by reason of therigid shaft 26 the other catch will be released at the same time. i V

31 indicates a sheath of substantially semi.- cylindrical form securedat its rear edge to the crossbar '14 and extending beneath the casing.The front edge portion of the sheath constitutes a line gage at 32cooperating dire'ctly with the'front portion of the casing V or with thesheet of the copy rolled thereon.

(See Fig. 4). sheath is mounted upon a rod 33 which projects throughpairs of ears 34 formed coincidentally with the formation of openings 35in said sheath to accommodate a plurality of rollers 36 journaled uponthe rod. The ends of the rod are supported in a pair of hangers 37 and38 hung respectively-upona and 38 at the front ends a finger piece orlever 39which when pressed rearward lifts the rod 33 carrying itshangers 37 and 38 and the, front portion of the sheath away from thecasing releasing any hold thereof upon the paper.

As a'further description of the operationof the rotatingcylinder,serving as a casing or holder, for a rolled book or rollv ofmanuscriptto be copled and whose two relatively parts serve as agripping holder movable for the upper, end of a sheet to be copied,

mechanism externally erating with the sheet gage and guiding means, andalso the bail including the bar 52 serving tothrow the of the: rollercotploose lowerendofthe sheefiovero'ut "of "Said front portion of thenection it is of paper as a line therange of the operators vision, Fig.8 indicates the relation of the parts above mentioned at the moment ofthe gripping of the upper end of the sheet S between the two parts ofthe cylinder, the paper being thus held in gripped position bycooperation between the catches 25 and lugs 27. It will be understoodthat the parts just referred to coeperate in the manner illustrated upona single loose sheet in substantialy the same manner as upon a sheetprotrudingthrough the casing from a roll or book within the casing. Fig.9 is a view similar to Fig. cylinder after a complete rotation thereof,all of the sheetex'cept the lower end being wrapped around the cylinderand the bail shown in full lines as about to bereleased to throw theloose end of the sheet upward and rearward to the dot and dash lineposition shown at the left side thereof. It will be understood thatduring the rotation of the cylinder between the positions of Figs. 8 and9 the bail bar 52 by riding or wiping over the rear portion of thestationary mechanism will be brought down upon the outside of thecylinder and into the groove or pit 52 provided therefor at the front orfree gripping edge of the upper port1on 16 cylinder. After the, sheet isgripped as indicated in Fig 8 the operator by a simple movement gives aquick spin or rotation of the cylinder and at the end of this rotation,as indicatedin F ig9, the loose or lower end of the sheet way by theswinging of the bail around its axis 51 and bythis time the first lineof matter on the sheet will be brought into view just abovethe line gageFig. 10 indicates the result of the succeeding step by step actuation ofthe cylinder as" a result of the transcribing operation. This figureshows the lowerend of the sheet as still being located between the linegage or griping rollers and cylinder. At this coni to be noted that theoperation of the device is not dependent upon any particular length ofsheet. Fig. 11 is a view showing the action of the bail and upper part16 of the cylinder when the extension 39 is pressed rearward far enoughto open the cylinder, it'being remembered that the first part of thisactuation of theiextension 39 serves to release the gripping rollers andline gage while the latter part releases the catches 25. The preferredconstruction is such that the circumference of the cylinderapproximately equals the length of the sheet, but if the sheet is longerand is wrapped more than once around the cylinder it ma 1 be necessaryto reverse the rotation of the cylinder slightly by the operation of thehand upon one of the knobs 21 to effect the release of the and betweenthe sheet and the is thrown over out of the- 8 showing the can bemanipulated in no other we sheet and opening of the cylinder as shown inFig. 11. This apparatus is designed especially for copying ortranscribing from ordinary folded court files or abstracts that asconveniently as within the hollow cylinder.

At either end of the device, prefe 'ably at the right, the short shaft19. This lever carries a pivotally mounted pawl 11, the point ofwhichprojects upward for cooperation with a fine toothed ratchet wheel 42concentric with and fixed to the axis 19; A light spring 43 is connectedto the pawl for the purpose of causing the point of the pawl toiengagethe teeth of the ratchet wheel when the lever 10 is lifted to actuatethe casing. The pawl, however, is provided with a rearwardly projectingrounded end 44; cooperating'with a V-ended stop so connected to abracket -15 fixed to and extending downward from the bracket 17. Theseparts are so designed that when the lever 10 is returned bythe spring toits idle position .the rounded end or tail piece M of the pawl isreceived into the V of the stop 45 whereby the point of the pawl iswithdrawn from the ratchet wheel against the force of thelight spring453 so the pawl is normally held free from theratchet wheel and thus theoperator by grasping either of the wheels or knobs '21 may rotate thecasing rearward as well as forward at any time. \Vhen, however, thelever 4L0 is lifted to actuate the casing forward the pawl 41 willimmediately engage a tooth of the ratchet wheel since the tail piecethereof will-immediately leave the notch or V of the stop 4:5.duringsuch movement of the lever 10. The stop 15 consequently constitutes ameans ,to limit the downward movement of the lever 40.

The front end of the bracket 17 orv any device connected thereto servestosupport an adjustable carnv shaped abutment 46 pivoted at 7 to thebracket. The bracket is provided with a'series of notches or pits -18into which a spring operated stud 4:9 is adapted tosnap and temporarilyhold the cam 4:6 in any desired position. The portion of the brackethaving the holes or pits 48 is preferably graduated to represent variouswidths or distances between lines of matter to be copied. The fingerpiece 46 of the adjustable cam thus operates between relatively fixedcars 16 but projects forward therefrom so that the manipulation of thecam may be easily effected by the operator by compressionaction,grasping said finger piece and the ear toward which it is to be movedbetween the thumband finger so that the ear constitutes a fixed abutment or'fulcrum to make the action positive and reliable.

At 50 I show a pair of levers connected to the ends of a rock shaft 51on the out- I provide a lever 40 pivoted uponv side of the ends of thecover section 16 of the casing, the outer ends of these lovers areconnected by a steel ribbon 52 or the like. Said rock shaft 51 iscontrolled on the inside of the casing by a spring 53, the tendency ofwhich is to throw the bail constituted by the two lovers and steelribbon rearward while the casing is being rotated. The rear or convexedges, however, of the levers 50 are adapted to ride upon rubber rollers11 mounted upon the crossbar 1.4: whereby the steel rib'bon 52 is swunginward against the surface of the casing while the casing rotates, thelength of the lovers being so designed that said ribbon will just bridgeover the joint between the free edges of the casing parts therebyrelieving any depression or offset for the rollers 36 that otherwisewould be incident to the edge of the casing which preferably is madesomewhat rounded to prevent any damage to the sheets of copy projectingtherefrom.

1n the practical operation of this copy holder any number of sheets suchas a note book, loose leaves or part of a roll of matter to be copiedare projected outward and downward over the line gage portion of thesheath, the bulk of the note book or other collection of sheets orleaves pertaining to the same copy being rolled up in any convenicntmanner and placed within the easing. The casing will now be closedeither preliminary to or as a. consequence of the rotation impartedthereto by one or the other of the finger pieces or knobs 3'1. \Vhilethe casing is thus being given a complete rotation the bail is rolledbetween the sheet and easing so that when the rotation is complete andthe ribbon portion of the bail passes the line gage the spring 53pertaining thereto will snap the bail upward and rearward, causing theend of the sheet to be carried rearward therewith and held out of theline of vision and thereby the sheet to be copied beginning at its upperend is presented in proper position for this purpose. In this conditionthe casing may be given a step by step rotation until the sheet iseopied,-then by touching the wing 30 the casing may be opened andanother sheet will be adjusted for treatment in the manner alreadydescribed. In withdrawing the sheet from the machine, the line gage orsheath will be released therefrom by applying the thumb or finger to theextension 39. 1-\.ttention now called to a wing 54- shown asconstituting a rearward extension of the hanger 38 and having an areshaped rear edge cooperating with a lug 55 formed on the adjacent hook25. The curvature of the wing edge is such that in normal position thelug 55 as it is carried with the hook around the axis of the casingj'iasses along a path parallel to but spaced slightly from said'edge.The finger piece 39 in addition knob 21 and apply his thumbjto piece 39whereupon an easy pressure 'on'the throw the hangerSS around its pivot38 and-so release This brings the curved edge of the wing 5-1 intowiping engagement with" that the paper may be'releasedto serving torelease the line gage from its gripplng position on the paper alsoconstitutes a'ineans to open the casing.- Thegrasp thef the fingeroperator to release the paper will finger piece Will immediatelythepaper.

without opening the casing if desired, or if the casing is lease both ofthe hooks 25. Obviously the extent of swinging movement of the hanger 38or wing 54 in the act of releasing the" paper, but without releasing thehook, will depend uponthe normal clearance between or the length of the"the lug 55 and winged: hooks that extend beyond the lugs '27. I thusprovide a simple mechanical contrivance, one that is easily manipulatedfor accomplishing two distinct objects or func-' tions. The length ofthe arc of the Wing 5% is such that the wing will engage the lug 55 forthe purpose of unlocking and opening the casing atany point in aconsiderable range relative to the joint in the casing be yond the linegage. fore, that when'the finger piece 39 is actuated to cause theunlocking and opening of the casing by reason of the cooperation betweenthe wing 54 and the lug .55, not only willthe casing be opened so thatthe material therein may be removed, but also the same action of thefinger piece in lifting theline gage away from the casing or sheet willinsure as may be desired;
